My workaround is to fix xauth settings in /etc/gdm3/Xsession by adding the lines
# PSz 31 Jan 2014 Fix up weird xauth setting that upsets "ssh -X". xauth list 2>/dev/null | perl -ne ' ($h,$s,$m,$c)=m/^#ffff#((?:3\d|2e)*)#:(\S+)\s+(MIT\S+)\s+([0-9a-f]{32})$/ and $h=~s/2e/./g and $h=~s/3(\d)/$1/g and system "xauth add $h:$s $m $c"; exit' to that script, somewhere before the SESSIONFILES=$(run_parts $SYSSESSIONDIR) block.
